Description

Technical Field

[0001] This invention belongs to the field of building decoration and construction technology, and particularly relates to a wall panel and decoration construction process. Background Technology

[0002] Hospital clean areas such as operating rooms, ICUs, and delivery rooms have extremely high requirements for the cleanliness, airtightness, impact resistance, ease of cleaning, and antibacterial properties of the indoor environment. Traditional wall decoration typically employs on-site wet work methods, such as tiling after plastering or on-site wall panel pasting. This approach has the following technical drawbacks: wet work requires layered construction and curing, resulting in long waiting times between processes and a long construction cycle. It is also significantly affected by ambient temperature and humidity, making it difficult to meet the rapid construction needs of modern hospitals; dust and waste generated from on-site cutting and mixing severely impact the construction environment; relying on manual plastering or simple full-adhesion pasting greatly affects the wall surface flatness, which is highly dependent on the operator's skill level and cannot meet the high flatness requirements of cleanrooms; traditional full-adhesion pasting or clip-on fixing methods also suffer from poor flatness, easy detachment, or dust accumulation in gaps; the caulking gaps at the joints of traditional wall panels are prone to aging and cracking over long-term use, creating unsanitary corners that breed bacteria and affect the hygiene and safety of the cleanroom; and inadequate treatment at junctions between walls and floors, walls and ceilings, and wall corners leaves gaps, affecting pressure differential control in the cleanroom and making it difficult to maintain a stable clean environment.

[0019] The following will refer to the appendices in the embodiments of the present invention. Figure 1-9 The technical solutions in the embodiments of the present invention are clearly and completely described herein. Obviously, the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of the present invention.

[0020] Example 1: Inorganic coated wall panels suitable for ICUs, delivery rooms, auxiliary rooms, and hemodialysis centers A wall panel includes a wall body 1, a ground joint, a top joint, and a side joint.

The base board 3 is a calcium silicate board with a thickness of 10mm, fixed to the keel frame 2 with self-tapping screws 20. The decorative panel 4 is an inorganic coated board with a thickness of 6mm.

[0022] The decorative panel 4 and the baseboard 3 are connected by a combined adhesive fixing structure. This structure includes double-sided adhesive strips 18 and structural adhesive dot matrix 19. The double-sided adhesive strips 18 are arranged along the longitudinal and transverse directions of the back of the decorative panel 4, and are located at least around the perimeter of the decorative panel 4, 10mm from the edge of the panel 4. The structural adhesive dot matrix 19 is distributed in a dotted pattern within the area defined by the double-sided adhesive strips 18, with a spacing of 150mm and a thickness of not less than 5mm. The thickness of the structural adhesive dot matrix 19 is greater than the thickness of the double-sided adhesive strips 18, allowing for adjustment of the flatness of the decorative panel 4 through compression allowance.

[0023] The ground joint is located at the junction of the bottom of the wall 1 and the ground 5, and includes an arc-shaped base 6 and a flexible skirting layer 7. The arc-shaped base 6 is laid at the inside corner formed by the wall and the ground 5 and is in the shape of an inwardly concave arc. It is formed by scraping and molding a mixture of 108 glue and cement, with an arc radius of R50. The flexible skirting layer 7 is formed by continuously turning up a flexible roll material 8 laid on the ground 5 after being heat-bent on the surface of the arc-shaped base 6. The flexible roll material 8 is a homogeneous through-wall PVC roll material with a thickness of 2mm and an upward turning height of 100mm. The upward turning part of the flexible skirting layer 7 is attached to the lower edge of the decorative panel 4.

[0024] As an alternative structure for the floor joint, a skirting board backing plate 21 is provided at the lower edge of the decorative panel 4, and the skirting board backing plate 21 is recessed inward by 4mm relative to the upper decorative panel 4. The flexible skirting layer 7 is adhered to the surface of the skirting board backing plate 21, and the outer surface of the adhered skirting layer is recessed inward by 2mm relative to the outer surface of the upper decorative panel 4. Corner guards 9 are used at the corners, and the corner guards 9 protrude from both ends of the wall and floor 5, gradually forming a transition area 10 with sealing and embedding material, and a bottom sealing layer 11 is provided.

[0025] The top joint is located at the junction of the top of the wall 1 and the ceiling 12 structure, and includes an aluminum alloy spherical corner piece 13. A rubber and plastic insulation layer 14 with a thickness of 20mm is attached to the concave side of the aluminum alloy spherical corner piece 13. A top sealing layer 15 is provided on the convex side to the joint between the ceiling 12 structure and the decorative panel 4.

[0026] The side joint is located at the corner of the wall or at the junction of the wall and the door frame or equipment embedding area. It includes a corner strip 16 that is pressed against the external or internal corner formed by the decorative panels 4 of two adjacent walls, and a corner sealing layer 17 that fills the gap between the corner strip 16 and the decorative panel 4. The corner strip 16 is an aluminum alloy arc strip. The bottom sealing layer 11, the top sealing layer 15 and the corner sealing layer 17 are all formed by curing neutral silicone sealant.

[0027] A wall panel installation process includes the following steps: S1. Partition wall layout: Based on the design and construction drawings, mark the position lines of the partition walls, the frame lines of the door and window openings, and the position of the edge lines along the top joists on the ground 5.

[0028] S2. Construction of the ground sill base: After roughening, cleaning and moistening the ground surface (base 5), pour a 100mm thick cast-in-place concrete wall base. To facilitate the fixing along the ground joists, pre-embed anti-corrosion wooden blocks in the base, with a spacing of 600mm along the length direction.

[0029] S3. Install the top joists, bottom joists, and door frame joists: Install the top joists and bottom joists according to the layout position, and fix them to the main structure with nails. The spacing between the nails should not exceed 600mm.

[0030] S4. Vertical keel spacing and installation: Based on the location of the partition wall and door opening, after the top and bottom keels are installed, determine the spacing of the vertical keels according to the specifications and modules of the decorative panels. When the width of the decorative panel is 1200mm, the vertical keel spacing is set to 400mm; if non-modular spacing is encountered, adjust the arrangement to ensure that non-whole panels are located in the middle of the wall, avoiding narrow strips of panels near the door opening frame. Insert the vertical keels according to the determined spacing positions, with their upper and lower ends embedded in the grooves along the top and bottom keels respectively. After verticality correction and positioning, use keel clamps to press and fix them. Keels near the wall or column are reliably connected to the wall or column body using nails or wood screws.

[0031] S5. Installation of Horizontal Keel and Special Node Frame: Install horizontal continuous keels. When the partition wall height is greater than 3m, add horizontal retaining keels according to design requirements and fix them with blind rivets or bolts. For special node areas such as partition wall corners, add additional keels, diagonal braces, or double parallel vertical keels for reinforcement according to the drawings. Decorative wooden door frames are fixed to the vertical keels of the opening with screws, and the connection between their beams and horizontal keels is also done in the same way.

[0032] S6. Fix the first side baseboard 3: Cover the surface of the keel frame 2 with the baseboard 3 and tighten it with self-tapping screws. Installation should begin at the doorway or one end of the wall without a doorway. The fixing requirements for the calcium silicate board are: screw spacing at the board edge should not exceed 200mm, and screw spacing in the board center should not exceed 300mm; the distance between the screw and the board edge should be controlled between 10mm and 16mm. When tightening the screws, ensure the board is tightly fitted to the keel.

[0033] S7. Installation and concealed acceptance of pipelines and equipment in the wall: Install electrical conduits, electrical boxes and electrical equipment in the cavity of the keel, and conduct concealed works inspection and acceptance after completion.

[0034] S8. Installation of the other side baseboard 3 and joint treatment: The process requirements for installing the other side of the calcium silicate board are the same as those for the first side, and the joints of the two sides must be staggered. If it is designed as a double-layer board, the joints of the second layer board should also be staggered from the joints of the first layer board and should not overlap on the same keel. Taking the flat joint treatment as an example: After cleaning the dust in the joint, use a scraper to embed putty into the joint and fill it and smooth it; after the joint putty has solidified, apply a thin layer of thin glue-like putty about 1mm thick at the joint, then attach the joint tape, and use a scraper to smooth and compact it from top to bottom in one direction to remove air bubbles.

[0035] S9. Install decorative panel 4: Treat the nail heads of the baseboard 3 with rust prevention, clean the wall surface of dust and debris, and repair and smooth it. Mark the dividing lines for decorative panel 4 on the baseboard 3 according to the wall layout plan. When decorative panel 4 is an inorganic coated board: Adhere double-sided adhesive strip 18 to the surface of the baseboard 3 or the back of the decorative panel 4, 10mm from the edge, and remove the film covering the adhesive strip; apply structural adhesive in dots at 150mm intervals within the area enclosed by the double-sided adhesive strip 18, with an adhesive thickness of not less than 5mm. Press the decorative panel 4 onto the baseboard 3, adjust the flatness of the board surface using the filling properties of the structural adhesive, and allow it to cure for 24 hours. Temporarily support the ceiling 12 areas with wooden support frames, removing them after the adhesive has cured.

[0036] S10. Fabrication of the floor joint: At the inside corner where the wall and floor 5 meet, a mixture of 108 glue and cement is scraped and molded into an R50 arc-shaped base 6. When laying the homogeneous through-wall PVC roll material of the floor 5, its edges are heat-bent and continuously turned up 100mm along the arc base until it is tightly attached to the lower edge of the decorative panel 4, forming an integrated skirting board structure. As another embodiment, a skirting board backing plate 21 is preset at the lower edge of the decorative panel 4, and the skirting board backing plate 21 is recessed 4mm inward relative to the upper decorative panel 4; the flexible skirting layer 7 is pasted on the surface of the skirting board backing plate 21, and the outer surface of the pasted skirting layer is recessed 2mm inward relative to the outer surface of the upper decorative panel 4.

[0037] S11. Fabrication of the ceiling joint: The ceiling 12 is installed on the floor slab 22. Aluminum alloy ball joints 13 are arranged at the top of the wall 1. The flanges at the ends of the aluminum alloy ball joints 13 are welded to the keel frame 2. The joint is filled with 20mm thick insulation cotton, and a 20mm thick rubber and plastic insulation layer 14 is pasted on the concave side of the aluminum alloy ball joints 13. The keel frame 2 is welded to the keel of the ceiling 12.

[0038] S12. Sealing treatment: Neutral silicone sealant is injected into the joint between the decorative panel 4 and the ceiling 12 at the top of the wall 1, at the corners of the wall, and around the openings of various electromechanical terminals on the decorative panel 4 to complete the overall airtight sealing.

[0039] Example 2: Magnesium oxide composite wall panels suitable for laboratory and supply room The difference between this embodiment and embodiment 1 is that the decorative panel 4 and the base plate 3 are integrally formed glass magnesium composite panels. The glass magnesium composite panels are composed of a panel and a non-combustible filler material, with a thickness of 50mm. Adjacent glass magnesium composite panels are fixed by interlocking with aluminum or channel aluminum. The joints and corners are sealed with neutral silicone sealant.

[0040] During installation, the lower section uses channel aluminum and is fixed to the ground at intervals of 0.3m to 0.5m with plastic expansion bolts. The upper section uses pressed channel aluminum; for rigid ceilings, it is fixed to the ceiling panel with a nail gun, while for flexible ceilings, it is suspended by hangers. The vertical panels are installed into prefabricated components according to the layout diagram, with adjacent magnesium oxide composite panels locked together using T-shaped aluminum interlocking joints. The ceiling panel is fixed using T-shaped aluminum joints and connecting plate blind rivets.

[0041] The remaining structure and construction steps are the same as in Example 1.
